How big is the gas tank on a 2004 Ford Explorer?

The fuel tank in a 2004 Ford Explorer holds 22.5 gallons of gas.
Ford’s popular sport utility vehicle was available with either a V6 or V8 engine for the 2004 model year, and came in five trims: NBX,
, and
Eddie Bauer
. While some Ford vehicles have different gas tank sizes depending on their configurations, the 2004 Explorer used the same fuel tank on all models, regardless of trim level or what engine it was equipped with.

How to check your 2004 Ford Explorer’s gas tank size

If you don’t want to take our word for it and prefer to check the capacity of your 2004 Explorer’s gas tank for yourself, there are a few ways you can go about it.

Measure the gas tank

As long as you’ve got a measuring tape on hand, you can determine how much gas your car can hold with some simple math. Just find the fuel tank and measure its width, length, then height, and multiply those numbers together. Next, divide the result by 231—that’s the number of cubic inches in a gallon—to get your tank’s fuel capacity.

Check your owner’s manual

Another way to check the size of your Explorer’s gas tank is by consulting your owner’s manual. Just scan the table of contents for phrases like “fuel tank” or “gas tank,” and turn to the listed page to find its capacity.

Drive till empty, then fill it up

If you don’t have your owner’s manual handy and don’t feel like crawling under your vehicle to take your own measurements, you can find your 2004 Explorer’s gas capacity by driving it until your gas gauge reads “E”. Then, when you fill up the car, check the meter on the gas pump to determine how much fuel it took to fill your tank. 
This method won’t get you an exact measurement, but it should give you a general idea of how much gas your tank can hold.

How to save on fuel costs with a 2004 Ford Explorer

According to the Environmental Protection Agency (EPA), a 2004 Ford Explorer only gets about 16 miles per gallon. That’s not great fuel economy to begin with, and as gas prices inch dangerously close to five dollars per gallon in many areas, it’s more important now than ever to conserve fuel where you can.
Despite its low EPA rating, you don’t need to resign yourself to pouring all your hard earned dollars down your car’s gas tank. Here are a few things you can do to reduce how much money you spend on fuel:
  • Stay on top of
    basic maintenance
    . It might be tempting to skip out on that $75 oil change, but neglecting important car-care essentials can cause wear and tear on your vehicle and decrease its fuel economy.
  • Drive safely. Things like speeding, aggressive driving, and slamming on your brakes all reduce your vehicle’s fuel efficiency.
  • Don’t idle. Letting your engine run while the car is in park consumes gas for no reason. You’ll save fuel by simply shutting the vehicle off while you’re stopped, and turning it back on once you're ready to drive again.
